CI框架中如何异步渲染移动端列表页的分类新闻？

<code class="javascript">$('.category').click(function() {
    let categoryId = $(this).data('id');
    $.ajax({
        url: '/news/get_category_news/' + categoryId,
        type: 'GET', // 或POST
        dataType: 'html', // 或'json'
        success: function(data) {
            $('#news-container').html(data);
        },
        error: function(xhr, status, error) {
            console.error("AJAX请求失败:", error);
        }
    });
});</code>

<code class="php"><?php
defined('BASEPATH') OR exit('No direct script access allowed');

class News extends CI_Controller {

    public function get_category_news($categoryId) {
        $this->load->model('News_model'); // 加载模型
        $newsData = $this->News_model->getNewsByCategory($categoryId);
        $newsHtml = $this->load->view('news_list', ['news' => $newsData], TRUE); // 加载视图并返回HTML
        echo $newsHtml;
    }
}</code>

<code class="php"><?php
defined('BASEPATH') OR exit('No direct script access allowed');

class News_model extends CI_Model {

    public function getNewsByCategory($categoryId) {
        return $this->db->where('category_id', $categoryId)->get('news')->result_array();
    }
}</code>

<code class="php"><?php foreach ($news as $item): ?>
    <div class="news-item">
        <h3><?php echo $item['title']; ?></h3>
        <p><?php echo $item['content']; ?></p>
    </div>
<?php endforeach; ?></code>
